Robert Ewart (1859 - 1929)
Robert was the son of Henry (Harry) Ewart and elder brother of John Peter Ewart. I have recently found references to a Mrs Ewart so i now believe he did marry at some point. Robert spent his life walking, prospecting and exploring the hostile West Coast of Tasmania.

It has been suggested that Robert may have been one of the first men to climb Mt Ossa (Tasmania's highest peak at 1617m)
..."Mt Ossa may have been first climbed by either the trackcutter Robert Ewart or the trapper and prospector Paddy Hartnett from his base at Du Cane Hut" Mt Ossa
The following newspaper reports and book excerpts give a description of Robert and the work he carried out.
